Abstract

Objective : This study was designed to assess the heart rate variablitv of patients with Parkinson's disease according to Hoehn-Yahr stage. Methods : Subjects were voluntarily recruited by newspapers and internet. All the subjects are confirmed as idiopathic parkinson's disease by a neurologist. The patients were grouped by Hoehn-Yahr(H-Y) stage. Heart rate variability was measured for 5 minutes after 5 minutes' bed rest. Subjects were comprised of 3 groups which were H-Y stage I (n=14), H-Y stage H(n=9), H-Y stage III(n=7). We compared the heart rate variability of each groups by one-way ANOVA test. We also studied the relationship between UPDRS score and Heat rate variability components (SDNN, RMS-SD and TP) by pearson correlation analysis and simple linear regressin analysis Results: Age, duration was matched among groups. SDNN, RMS-SD, TP were significantly decreased as H-Y stage increased(p<0.05). Especially there was significant difference between H-Y stage I and III group(p<0.05). But other components(Heart rate, LF, HF, LF/HF ratio) were not showed significant difference. SDNN, RMS-SD and TP were significantly decreased as UPDRS scores increase(p<0.05). Conclusion : This study suggests that the function of the autonomic nervous system decreases as Parkinson`s disease progresses.

본 저자는 2004년 3월 9일부터 2004년 5월15일까지 경희의료원 침구과 외래를 내원한 특발성 파킨슨병 환자를 대상으로 하여 파킨슨병 증상의 호전도를 판단하는 임상척도인 H-Y stage에 따른 HRV를 관찰한 결과 다음과 같은 결론을 얻었다. 1. 시간영역분석에서 H-Y stage I, II, III 그룹의 SDNN은 $28.21{\pm}10.10$, $22.25{\pm}11.26$, $14.57{\pm}5.31$으로 그룹 I과 그룹III 간에는 유의한 차이가 있었다(P<0.05). RMS-SD는 $19.23{\pm}13.27$, $14.63{\pm}6.44$, $6.44{\pm}2.32$ 으로 역시 그룹 I과 그룹III 간에는 유의한 차이가 있었 다(p<0.05). 2. 주파수영역분석에서 TP는 H-Y stage Ⅰ, II, III 그룹에서 각각 $499.86{\pm}345.45$, $243.72{\pm}212.22$, $99.44{\pm}51.01$로 ANOYA 검정결과 p-value가 0.007로 매우 유의 있었으며, 사후 검정에서는 그룹 I과 II, 그룹 II와 III에서는 유의한 차이가 없었으나 그룹 I과 III에서는 매우 유의한 차이가 있었다(p<0.01). LF는 H-Y stage I과 III 그룹에서 유의한 차이가 있었으나(p<0.05) VLF, HF, LF norm HF nonm LF norm, LF/HF ratio에서는 각 그룹 간 유의한 차이가 없었다. 3. SDNN, RMS-SD, TP가 UPDRS 총점이 증가함에 따라 유의성 있게 감소하는 경향 (p<0.05)을 보이는 것으로 보아 파킨슨병이 진행함에 따라 자율신경계의 활동성이 저하될 것으로 보인다.
